Abstract
An optical module capable of connecting signal lines to an external substrate easily without causing any degradation of the transmission characteristic is disclosed. The optical module comprises an optical element mounting block having an optical element mounting section and an optical fiber guide, and a wiring lead integrated resin substrate having a ferrule holding section, an optical element mounting block housing section, and wiring leads, where at least a part of the wiring leads are provided by signal lines in a coplanar guide structure entirely formed on the wiring lead integrated resin substrate such that a characteristic impedance does not change when the wiring leads are electrically connected to external wirings.
